The Danger Is That The Compromises And

As Species Are Exterminated By Shifting Climate Zones, Ecosystems Can Collapse, Destroying More Species.

'goals' And 'caps' On Carbon Emissions Are Practically Worthless, If Coal Emissions Continue, Because Of The Exceedingly Long Lifetime Of Carbon Dioxide In The Air.

If Humanity Wishes To Preserve A Planet Similar To That On Which Civilisation Developed And To Which Life On Earth Is Adapted, Paleoclimate Evidence And Ongoing Climate Change Suggest That Co₂ Will Need To Be Reduced From Its Current 385 Ppm [parts Per Million] To At Most 350 Ppm... If The Present Overshoot Of This Target Co₂ Is Not Brief, There Is A Possibility Of Seeding Irreversible Catastrophic Effects.

The Most Difficult Task, Phase-out Over The Next 20-25 Years Of Coal Use That Does Not Capture Co₂, Is Herculean, Yet Feasible When Compared With The Efforts That Went Into World War Ii. The Stakes, For All Life On The Planet, Surpass Those Of Any Previous Crisis. The Greatest Danger Is Continued Ignorance And Denial, Which Could Make Tragic Consequences Unavoidable.

We Have At Most Ten Years—not Ten Years To Decide Upon Action, But Ten Years To Alter Fundamentally The Trajectory Of Global Greenhouse Emissions.
